Thought of the Day - An upgrade in air travel

75802-576756-thumbnail.jpgUnited is now charging to sit in their 'Economy Plus' section.  It used to be that if you were a frequent flier you could get upgraded to that section no charge.

This was on a recent flight on a 777.  The back of the bus was loaded to the gills.  The Economy Plus section was about 1/3 open.

I wonder how their load management software handles this.  If they oversell the economy section, do they put people into the economy plus section, or keep them off the plane?
